1. Use the built-in Vector3 class instead of creating custom vectors.
2. Avoid creating too many vectors unnecessarily. Instead, reuse existing vectors wherever possible.
3. Use Vector3.SmoothDamp for smooth and natural movement.
4. Avoid using Vector3.Distance for distance calculations as it is slower than using the magnitude property.
5. Normalize vectors only when necessary to avoid unnecessary calculations.
6. Use Vector3.Cross for calculating the perpendicular vector.
7. Familiarize yourself with the different vector-related functions and properties available in Unity's documentation.
8. Use Vector3.Lerp for interpolating between two vectors.
9. Don't modify individual components of a vector unless necessary. Instead, use the provided methods and operators to modify them.
10. Understand the difference between local and world space when working with vectors in Unity.
